EVOLUTIONEVOLUTION

The predecessor of the spacemouse was the The predecessor of the spacemouse was the DLR controller ball.DLR controller ball.

redesigned the control ball idea with its redesigned the control ball idea with its unsurpassed optoelectronic measuring system unsurpassed optoelectronic measuring system and optimized it to reduce manufacturing costs and optimized it to reduce manufacturing costs to a fraction of its previous amount and thus to a fraction of its previous amount and thus allow it to approach the pricing level of high allow it to approach the pricing level of high quality PC mouse at least long-term.quality PC mouse at least long-term.

Spacemouse has its origins in the late Spacemouse has its origins in the late seventies when the DLR (German Aerospace seventies when the DLR (German Aerospace Research Establishment) started research in its Research Establishment) started research in its robotics and system dynamics division on robotics and system dynamics division on devices with six degrees of freedom (6 dof) for devices with six degrees of freedom (6 dof) for controlling robot grippers in Cartesian space.controlling robot grippers in Cartesian space.

CONCLUSIONCONCLUSION

The graphics simulation and manipulation of 3D The graphics simulation and manipulation of 3D volume objects and virtual worlds and their volume objects and virtual worlds and their combination is not only meaningful for space combination is not only meaningful for space technology, but will strongly change the whole technology, but will strongly change the whole world of manufacturing and construction world of manufacturing and construction technology . For all these applications we technology . For all these applications we believe there is no other man- machine interface believe there is no other man- machine interface technology comparable to Magellan in its technology comparable to Magellan in its simplicity and yet high precision. simplicity and yet high precision.
